* weka/filters/SplitDatasetFilter.java (stable-3-0-patches.1): "-V"
didn't get returned in all cases in getOptions.

* weka/clusterers/EM.java (stable-3-0-patches.2): Changed back from
using the normal estimator. The normal estimator gives a
probability rather than a density estimate. Now throws an exception
if the joint density overflows precision (normally happens when
there are many singletons or near singletons resulting in very
small standard deviations; this was causing some exceptions when
normalizing arrays). Added an option to set the minimum allowable
standard deviation for normal density estimation---increasing this
value can prevent density overflow. Added global info and tip text
methods.

* weka/clusterers/Cobweb.java (stable-3-0-patches.3): Stats were
not being updated properly when new nodes were considered for
addition to the tree.

* weka/associations/Apriori.java (stable-3-0-patches.1):
Fixed precision problem. Added extra check to stop rule generation
when min support equates to less than one instance.

* weka/clusterers/EM.java (stable-3-0-patches.1): Now uses a
NormalEstimator instead of custom code for normal distributions.
